Maintenance indicator zero reset Engine oil level indicator
After each service, the maintenance
indicator must be reset to zero.
The procedure for resetting to zero
is as follows:

 switch off the ignition,

 press and hold the trip distance
recorder zero reset button,

 switch on the ignition; the dis-
tance recorder display begins a
countdown,

 when the display indicates "=0" ,
release the button; the spanner
disappears. System which informs the driver
whether the engine oil level is correct
or not.
This information is displayed for a
few seconds when the ignition is
switched on, after the service infor-
mation.
The level read will only be correct if
the vehicle is on level ground and
the engine has been off for more
than 15 minutes.
Oil level correct
Oil level low
This is indicated by the fl ashing of

"OIL" , accompanied by an audible
signal and a message on the multi-
function screen.
If the low oil level is confi rmed by a
check using the dipstick, it is essential
that the level is topped up to prevent
damage to the engine. Oil level gauge fault
This is indicated by the fl ashing of

"OIL --" . Contact a CITROËN dealer.
Dipstick
Refer to the "Checks" section to
locate the dipstick and the oil fi ller
cap on your engine. There are 2 marks on
the dipstick:
- A = max; never ex-
ceed this level,
- B = min; top up the
level via the oil fi ller
cap, using the type
of oil suited to your
engine.
Following this operation, if you wish
to disconnect the battery, lock the
vehicle and wait at least fi ve minutes
for the zero reset to be taken into ac-
count.

TRAJECTORY CONTROL SYSTEMS
Anti-skid regulation (ASR) and
electronic stability programme
(ESP)
The anti-skid regulation (also known
as Traction Control) optimises trac-
tion to prevent skidding of the wheels,
by acting on the brakes of the driving
wheels and on the engine.
The electronic stability programme
acts on the brake of one or more
wheels and on the engine to keep
the vehicle on the trajectory required
by the driver.
Activation
These systems are activated auto-
matically each time the vehicle is
started.
They come into operation in the event
of a grip or trajectory problem. This is indicated by fl ashing
of this warning lamp on the
instrument panel. Deactivation
In exceptional conditions (starting a
vehicle which is bogged down, stuck
in snow, on soft ground...), it may be
advisable to deactivate the ASR and
ESP systems, so that the wheels
can move freely and regain grip.

 Press the "ESP OFF" button, lo-
cated in the centre of the dash-
board. Reactivation
These systems are reactivated au-
tomatically each time the ignition is
switched back on or from 30 mph
(50 km/h).

 Press the "ESP OFF" but-
ton again to reactivate them
manually.
If this warning lamp comes
on in the instrument panel
and the indicator lamp on the
button comes on, this indi-
cates that the ASR and ESP
systems are deactivated. Operating fault
If this warning lamp comes
on, accompanied by an au-
dible signal and a message
on the multifunction screen,
this indicates a malfunction of these
systems.
Have the systems checked by a
CITROËN dealer.
The ESP/ASR systems offer ex-
ceptional safety in normal driving,
but this should not encourage the
driver to take extra risks or drive at
high speed.
The correct functioning of these
systems depends on observation
of the manufacturer's recommen-
dations regarding the wheels (tyres
and rims), the braking components,
the electronic components and the
CITROËN assembly and operation
procedures.
After an impact, have these systems
checked by a CITROËN dealer.

you to view the position selected. Moving off

When the ignition is on, lighting of
the service warning lamp, accom-
panied by an audible signal and
the message "Gearbox faulty" in-
dicates a malfunction.
Consult a CITROËN dealer.
For safety:

 Position N can only be disen-
gaged if you are pressing the
brake pedal.

 If the gearbox is in position N

pressed, the corresponding warning
lamp(s) are displayed and a mes-
sage informs you that at least one of
these two conditions is not met.
In this case, the engine will not start,
recommence the above procedure.
Engaging reverse gear
To engage reverse gear, move the
selector to R .

Only attempt to select reverse gear
when the vehicle is stationary.

HILL START ASSIST (WITH THE 6-SPEED ELECTRONIC GEARBOX SYSTEM)
System which holds your vehicle tem-
porarily (approximately 2 seconds)
when starting on a gradient, the time it
takes to move your foot from the brake
pedal to the accelerator pedal.
This function is only active when:
- the vehicle is completely station-ary, with your foot on the brake
pedal,
- in particular conditions on a slope,
- with the driver’s door closed.
The hill start assist function cannot
be deactivated. Operation
Operating fault
If a malfunction of the system oc-
curs, these warning lamps come on.
Contact a CITROËN dealer to have
the system checked.

On an ascending slope, with the
vehicle stationary, the vehicle is
held

lease the brake pedal:
- provided you are in A or M on an
electronic gearbox,
On a descending slope, with the
vehicle stationary and reverse
gear engaged, the vehicle is held

momentarily
when you release
the brake pedal.
do not exit the vehicle while
it is being held in the hill
start assist phase.
If you need to exit the vehi-
cle with the engine running, manu-
ally apply the parking brake and

Manual operation
SPORT and SNOW
programmes
These two special programmes sup-
plement the automatic operation in
very specifi c conditions of use.
Position of the selector for manual
gear changing.
The fl ashing of the warning lamp for
the position requested signals that
this position is not yet obtained.
If the warning lamp is on fi xed, the
position is confi rmed.
Lighting of a dash in the rev coun-
ter indicates an operating fault. In
this case:
- a marked snatching may be felt
when selecting R for reverse
gear,
- the gearbox is locked in a gear,
- do not exceed 60 mph (approx. 100 km/h).
Consult a CITROËN dealer.
- A request to change gear is ac-
cepted only if the engine speed
permits it.
- For safety reasons, depending on the engine speed, a change
up or down may be performed
automatically.
- It is possible at any time to move from position D (driving in auto-
matic mode) to position M (driving
in sequential mode) or vice versa.
- The SPORT and SNOW modes
do not operate in sequential
mode.
SPORT programme "S"

 With the lever in position D and
the engine running, press but-
ton " S ".

Override of the programmed
speed
The accelerator pedal is equipped
with an end-of-travel switch. If you
action this switch by pressing the
pedal hard down, you can exceed
the memorised maximum speed at
any time.
During the time the speed is be-
ing exceeded, the displayed speed
fl ashes.
You have only to release the ac-
celerator pedal to return below the
maximum speed and render the
function active again.
If during the operation of the speed
limiter, the system is unable to keep
within the maximum speed (for exam-
ple on a steep descent or under heavy
acceleration) then the speed fl ashes.
Adapt your speed as necessary.
The function will re-engage when
your speed returns below the de-
sired maximum speed. Return to normal driving

 By moving the control 1 from po-
sition "LIM" to position 0 .

 By the engine stopping.
The speed previously chosen is still
memorised.
Operating fault
If there is a speed limiter malfunc-
tion, a message will display accom-
panied by an audible signal and
lighting of the service warning lamp.
Have it checked by a CITROËN
dealer.
On a steep downhill gradient or on
sharp acceleration, the speed limiter
will not be able to prevent the vehi-
cle from exceeding the programmed
speed.
Use of fl oor mats that are not ap-
proved by CITROËN may hinder
access to the accelerator pedal and
thus interfere with the functioning of
the speed limiter.
To avoid any risk of interfering with
the pedals:
- check that the fl oor mat is cor- rectly positioned,
- never use more than one fl oor mat.
